En skulle tru at partiene på venstresiden var de mest prinsippfaste, men det er ingen som er prioriterer sin kjernesak så høyt som høyrepartiene prioriterer de rikes mulighet til å bli rikere, ikke minst gjennom minst mulig skatt.

If you’ve ever attempted a meta-analysis, you’ll know that authors generally do a poor job reporting statistics. If you do this well, you’ll improve your chances of your work being included in a future meta-analysis.
Our paper on improving statistical reporting in psychology is now online 🎉
As a part of this paper, we also created the Transparent Statistical Reporting in Psychology checklist, which researchers can use to improve their statistical reporting practices

Under valgkampen lovte helseminister Jan Christian Vestre (Ap) tre milliarder til KI og medisinsk, teknisk utstyr i helsesektoren. – Løftebrudd, raser Høyres Erlend Svardal Bøe.

Science must be ethical and serve the public good. But it should not be ruled by popularity.
Truth is often uncomfortable. The call of the scientist is to seek that truth regardless. To expand the potential & wellbeing of humanity. Not shrink ourselves to the boundaries of convenience or approval.

Det er klart det er behagelig å være del av den eneste profesjonen med «en helhetlig forståelse av individ og samfunn». Samtidig blir jeg litt vemodig over at jeg ikke ble prest. Tenk å få være del av den eneste profesjonen med en helhetlig forståelse av himmel og helvete og alt imellom!
Ja, det er nok enkelt å bidra til realistiske forventinger til psykologer når man samtidig påstår smått grandiost at de har en *særegen kompetanse* *ingen andre* helseprofesjoner har.

And the distribution of SWD for psychotherapies for depression was very similar. In other words, we must say that there was no clear winner in terms of the population preferences -- or if you are brave enough or cynical enough, we must say there were only losers.
The observed smallest worthwhile difference in this study "means that the current 15% antidepressant benefit over no treatment was sufficient for 1 in 3 people to accept antidepressants given the burdens, but 2 in 3 expected greater treatment benefits."
The average SWD for antidepressants for MDD was RD of 20%, and SMD of around 0.5. mentalhealth.bmj.com/content/27/1...

That’s well put and has certainly been my experience with many smart clinical colleagues who fall into the trap of looking for HTE when there is no evidence for an average treatment effect. Effective treatments should reduce disease, creating anti-heterogeneity (treated pts -> more alike) #StatsSky

If we provide people with moderate to severe depressive episodes with realistic and balanced information about the effects of psychotherapy, potential adverse effects, costs, and burdens, only one-third consider it worthwhile trying psychotherapy.

Debatten mellom Trond Velken og Lars Lien i #dax18 viser at det er ikke nødvendig med professorkompetanse for å ha kompetanse på klinisk forskningsmetode, vurdere hvilken tillit man kan ha til resultater fra studier med ulike studiedesign og å innta en medisinsk konservativ tilnærming.

Good question. SWD and MIC (MID or MCID) are *completely* different. SWD is a between-group difference, typically between treatment and control, and in balance with the downsides of the treatment. MIC is a within-group pre-post change, typically in the absence of significant treatment burdens.
Is there a difference between smallest worthwhile difference (SWD) and minimum clinically important difference (MCID)?

The SWD (smallest worthwhile difference) for psychotherapies for depression was just about the same as that for antidepressants and only one in three people would be happy to initiate psychotherapies. www.cambridge.org/core/journal...

Det finnes ikke et enkelt «ja» eller «nei» svar på om vi skal bruke mer ressurser på psykisk helse. Svaret kommer an på (a) *hva vi får igjen* for de ressursene vi bruker på psykisk helse, og (b) hvilke andre ting/områder vi kunne brukt ressursene på og hva vi ville fått igjen for dette.
